Notes:
1) Please check with the actual devices when some commercial devices with RS485 interface are connected. The number of connected devices, transmission distance, and transmission speed may be different according to using transmission line.
2) For RS485 converter on the computer side, we recommend SI-35 and SI-35USB (from LINE EYE Co., Ltd.).
3) When using SI-35, SI-35USB or PLC from our company (which can be connected up to 99 units), up to 99 Eco-POWER METER can be connected. In case using this system with the other devices, up to 31 Eco-POWER METER can be connected.
4) With MODBUS (RTU) protocol, it works only with 8bit.

Notes :
1) | Dedicated CT are dedicated for low voltage under 440 V AC system. They can not be used for high voltage circuit. |
---|---|
2) | In each type of Eco-POWER METER excluding AKW8115, KW9M and KW2M, a combination of commercially secondary side 5 A CTs and dedicated CTs for 5 A is used for measuring high voltage circuits; For details, confirm with each respective user's manual. |
3) | Since dedicated CTs cannot be used when measuring with AKW8115, KW9M and KW2M, please be careful and do not purchase a dedicated CT by mistake. |
4) | For the AKW8115, KW9M and KW2M, CT with a secondary side current 1 A or 5 A is recommended. Please confirm the specification beforehand. |
5) | Dedicated CT are not included with Eco-POWER METERs. |
6) | Each dedicated CT includes a 1 m 3.281 ft relay cable, respectively. |
